+# RBAC required for the Fission multi-tenant NSWatcher.

+# The fission-executor ServiceAccount must be allowed to list and watch Namespaces
+# at the cluster scope so that NSWatcher can detect newly-labeled Namespaces.
+#
+# This is a read-only ClusterRole — no write permissions are granted.
+# Apply once per cluster after installing Fission:
